Materialists claim that what we have been saying here is a
philosophical view. However, to hold that the "external world", as we call it,
is a collection of perceptions is not a matter of philosophy but a plain scientific fact.
How the image and feelings form in the brain is taught in all medical schools in detail.
Everyone who believes in science, be he an atheist, Buddhist, or anyone who holds another
view has to accept this fact. A materialist might deny the existence of a Creator yet he
cannot deny this scientific reality. The inability of Karl Marx, Friedrich Engels, Georges
Politzer and others in comprehending such a simple and evident fact can be regarded as
normal to a certain extent considering the level of scientific understanding and
possibilities of their times but it is nevertheless startling. In our own time, science
and technology are highly advanced and recent discoveries make it easier to comprehend
this fact. Yet, it is indeed very surprising that there are still materialists who do not
understand it.

These facts, proven by the 20th century science, and particularly by
physics, clearly show that matter does not have an absolute reality and that everyone in a
sense is watching the "monitor in his brain".

However, materialists today, and especially Marxists, are coming to
realise this fact. This is why they say in their own publications that this subject is
more important than the theory of evolution, since it is directed straight to the essence
of matter. As they come to perceive the scientific realities and think on them, they have
gradually begun to comprehend the subject. If they consider the issue more honestly, we
think they will soon understand that the concept of matter (including the brain) that they
elevate so much is in fact an illusion perceived in the brain.
